In this video, we take you through the installation of the CTS Turbo test pipe/high flow cat for the Audi S4/S5 3.0T (B9). At the end of the video, we do a quick sound clip of the cold start and revs as well!

Really wish CTS would provide heat shielding as an option for this DP..
Does anyone know if the CEL comes on with the CTS Downpipe on a B9, if you're already APR Stage 1? What's our options?
is it ok with the CTS downpipe not having a heat shield? Can anything bad happen without the heat shield?
EMD… what gains did you see on the dyno with the CTS DP? They don't have figures listed on their site? What are the pros/cons of going with CAT vs. no CAT?
How come your website no long have this part? After install will engine light come on?
With a downpipe.. is a tune required ?
To me it looks like the factory set up is pretty healthy. I'm running a RENN tune on my S5 Sportback, not yet had a chance to rum a QM, but the car is able to do repeatable 0-60 runs in 3.5-3.7 sec range. With/without launch control. Great motor collab. between Porsche/Audi on the new 3.0T. Smooth with a massive hit of torque down low.
Why does title say High Flow Cat? This is an open pipe. Not a catalytic converter at all.
Is there any tune, that I can use with this product?
Is there a tune for it ? I assume it's useless to install a downpipe and run it with no tune
Thank you for posting,this is exactly what I am looking for on my B9 S5, does the sports cat run ok with standard ecu software with no check engine lights?
